Installing HEI Conversion Kits
Are HEI distributors worth it?
An HEI distributor is a great piece of equipment for an over-the-road car because it is completely self-contained. But without an external coil, a stock HEI cannot provide a strong spark at rpm levels commonly seen on the racetrack. Engines with higher compression or more horsepower also require a hotter spark.
Does HEI distributor have points?
A predecessor system called “Unitized Ignition” was optional on 1972 and 1973 Pontiacs. Most—but not all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system’s breaker points and condenser.
Do I need a ballast resistor with HEI?
Generally speaking (and every one i have ever delt with), an HEI does not need a ballast, they use 12 volt switched ign for power. So, the easy way to bypass the ballast system would be to run another wire from the ignition switch that powers when you turn the key on to your HEI unit.
Do I need a ballast resistor with electronic ignition?
Electronic ignition systems, whether factory Mopar or aftermarket, don’t utilize breaker points, thereby not actually needing a ballast resistor to control amperage through the pickup coil.
What happens when a ballast resistor goes bad?
If your ballast resistor is bad, your vehicle will not run and you will have to have it towed to the mechanic’s shop. The biggest sign your ballast resistor is bad is your vehicle will start, but immediately stop as soon as you let go of the key.
Does a ballast resistor need to be grounded?
A Ballast resistor should NEVER be grounded! The resistor limits the CURRENT going through the coil. Also, if you have a points ignition, it lengthens the life of the points greatly.
When your RPM go up and down?
Hi There, It sounds like you may have a dirty or failing idle air control valve causing your engine idle to fluctuate. The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor.
Why does my RPM go up and down while AC is on?
When the additional load of your AC compressor is added, it causes the computer to miscalculate and increase idle speed too much. Low Refrigerant in the AC System: If your AC system is low on refrigerant, it will make the compressor cycle on more frequently, increasing the load on your engine.
What gear is 40 mph?
What gear for which speed
Which gear is best for driving uphill?
When you’re driving uphill, change down to a lower gear to avoid the engine struggling to give enough power. Driving downhill, you can use a lower gear to increase the effect of engine braking and reduce the risk of overheating the brakes.
What gears for what speed?
Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear …
What does it mean when your car wont go past 40 mph?
“Limp Mode” – If your car won’t accelerate over 25 or 40 mph, it could have engaged ‘limp mode. ‘ It is also known as a limp home mode, and it acts as a preservation feature. It is meant to get you home, to an auto mechanic, or safely off the road without destroying your engine.
What are the symptoms of low transmission fluid?
Symptoms of Low Transmission Fluid
What does it mean when your car wont go past a certain speed?
Clogged or dirty fuel filter – A dirty filter, clogged with debris and other impurities will hinder the engine’s ability to receive the proper amount of fuel. If the fuel pump gives out or becomes clogged, it will be unable to supply fuel to the injectors and may result in poor acceleration, sputtering, or stall outs.
What causes a car not to pick up speed?
A dirty or clogged fuel filter is another reason for a car not accelerating like it’s supposed to when required to do so. With a dirty fuel filter, the engine won’t be getting enough fuel which means that the vehicle won’t be giving the acceleration performance that it should.
Why wont my car go when I press the gas?
If you car doesn’t move when you step on the gas pedal, this is usually an indication of a fuel system issue. However, it can also be an indication of engine problems or a stuck emergency brake. Typically before acceleration failure, you may find that your vehicle’s engine runs rough or frequently stalls.
Why won’t my car go over 30 miles an hour?
It may be down to a problem with the fuel injector becoming clogged-up, or it may be down to the fuel filter itself which may need to be replaced. The car may have too many miles on it and it may be a problem with bad transmission.
